Technical Field

[0001] This utility model relates to the field of embossing technology, and in particular to a device for improving the embossing quality of coated mineral wool sound-absorbing boards. Background Technology

[0002] Coated mineral wool sound-absorbing panels are multifunctional sound-absorbing materials made with mineral wool as the core raw material and a special film layer on the surface. They combine sound absorption and noise reduction, fire resistance, moisture resistance, and aesthetic appeal, and are widely used in places with high acoustic requirements. During the embossing process of coated mineral wool sound-absorbing panels, an embossing device is used. To improve embossing quality, the surface of the coated mineral wool sound-absorbing panels is usually preheated before embossing, which increases the accuracy of the embossing.

[0003] Existing preheating devices for embossing coated mineral wool sound-absorbing panels are generally hot air preheating devices. The coated mineral wool sound-absorbing panels move inside the preheating chamber of the device, and after the hot air blown out by the hot air blown out, it acts on the surface of the coated mineral wool sound-absorbing panels, thus performing preheating treatment. However, in existing hot air preheating devices, the hot air blowing pipes cannot be adjusted, resulting in an inability to adjust the range of hot air blowing. For coated mineral wool sound-absorbing panels with different preheating requirements, the hot air preheating range cannot be changed according to the actual situation, resulting in poor flexibility and adaptability, and generally mediocre performance.

Detailed Implementation

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0014] like Figures 1-4As shown, a device for improving the embossing quality of coated mineral wool sound-absorbing panels includes a base 1, a preheating box 2 mounted on the base 1, a rotating shaft 3 inside the preheating box 2, a conveyor belt 4 mounted on the rotating shaft 3, a hot air blower 5 fixed to the top of the preheating box 2, and a blowing structure 6 mounted on the top of the interior of the preheating box 2. Support legs 7 are mounted on the lower end of the base 1 and are threadedly connected to the base 1. A drive motor is mounted on the preheating box 2 and connected to the rotating shaft 3.

[0015] Before embossing the coated mineral wool sound-absorbing board, a hot air preheating device is used to preheat the surface of the board. This softens the coating layer, preventing breakage during embossing and improving embossing accuracy. During preheating, the device is placed on the support legs 7 at the bottom of the base 1. After starting the device, the drive motor rotates the shaft 3 inside the preheating chamber 2, which in turn drives the conveyor belt 4. The coated mineral wool sound-absorbing board is placed on the conveyor belt 4 and moved within the preheating chamber 2. During this movement, the hot air blower 5 generates hot air, which is blown out through the blowing structure 6 onto the board, preheating it. Once the board is removed from the preheating chamber 2, it is transported to the embossing station for the embossing process.

[0016] When needed, the blowing structure 6 can be adjusted to change the size of the air outlet, thereby changing the area of ​​hot air blown out. It is suitable for the preheating of film-coated mineral wool sound-absorbing panels with synchronous requirements. The structure is simple and easy to use.

[0017] According to the above implementation scheme, the blowing structure 6 includes an air guide shroud 601, a first air guide plate 602, a second air guide plate 603, a connecting shaft 604, and a gear 605. The first air guide plate 602 is fixedly installed at the top of the inside of the preheating box 2. The two connecting shafts 604 are respectively installed on the first air guide plate 602 and the second air guide plate 603. The first air guide plate 602 and the second air guide plate 603 are symmetrically installed inside the air guide shroud 601. The ends of the two connecting shafts 604 pass through the air guide shroud 601, and the ends of the connecting shafts 604 are connected to the gear 605.

[0018] The blower structure 6 also includes a rack 606, a fixing plate 607, a slide rail 608, a lifting rod 609, a servo motor 610, and an adjusting screw 611. The fixing plate 607 and the slide rail 608 are fixed to the end of the air guide cover 601. The lifting rod 609 is slidably mounted on the slide rail 608, and the end of the lifting rod 609 is fixedly connected to the rack 606 by screws. The rack 606 is meshed with the gear 605. The servo motor 610 is fixed to the fixing plate 607. The adjusting screw 611 is located between the two fixing plates 607, and the adjusting screw 611 is threadedly connected to the lifting rod 609. The end of the adjusting screw 611 is connected to the servo motor 610.

[0019] When using the blowing structure 6, the hot air generated by the hot air blower 5 enters the air guide hood 601 and is blown out onto the coated mineral wool sound-absorbing board under the guidance of the first air guide plate 602 and the second air guide plate 603. When the size of the air outlet needs to be adjusted, the servo motor 610 on the fixed plate 607 is activated. The servo motor 610 drives the adjusting screw 611 to rotate, thereby driving the lifting rod 609 to move along the slide rail 608. The rack 606 moves with the lifting rod 609. Under the action of the rack 606, the gear 605 drives the connecting shaft 604 to rotate, thereby changing the angle of the air guide plate. During this process, since the two sets of gears 605 and racks 606 are set synchronously, when the two racks 606 move synchronously, the two gears 605 rotate in opposite directions, achieving the purpose of synchronously adjusting the two air guide plates to flip in opposite directions. After the adjustment is completed, the hot air is blown out from the opening below the first air guide plate 602 and the second air guide plate 603 and acts on the coated mineral wool sound-absorbing board, thus completing the preheating treatment.

[0020] It should be noted that, through the set air blowing structure 6, a first air guide plate 602 and a second air guide plate 603 are symmetrically arranged inside the air guide cover 601. The two air guide plates are installed through a connecting shaft 604 and are used in conjunction with a gear 605, a rack 606, a fixing plate 607, a slide rail 608, a lifting rod 609, a servo motor 610, and an adjusting screw 611. The adjusting screw 611 can drive the lifting rod 609 to move the two racks 606, thereby using the gear 605 to rotate the connecting shaft 604, thereby changing the tilt angle of the air guide plate, and thus changing the size of the opening at the lower end of the air guide plate, thereby adjusting the air blowing area. It has high flexibility and adaptability. The two racks 606 and the two gears 605 are symmetrically arranged and can be adjusted synchronously in opposite directions to achieve synchronized adjustment. The transmission through the adjusting screw 611 and the lifting rod 609 can ensure the stability after adjustment and guarantee the effect of use.
